“RTK From the Sky” technology has been integrated into the core of the TerraStar-C PRO corrections service. As a result, TerraStar-C PRO provides centimeter-level accuracy, not just in open-sky environments but also across challenging conditions created by buildings and foliage. TerraStar-C PRO now converges in less than three minutes by utilizing quad-band receiver and antenna technology to leverage modernized BeiDou 3, GPS III and Galileo E6 signals. The resulting process generates state-of-the-art corrections for all GNSS frequencies. The service improvements are accessible through the 7.08.10 firmware release for users of OEM7700, OEM719 and OEM729 cards and their associated enclosures for land and air applications.

A north orientation mark is being added to the TW3000 family of Accutenna precision antennas and the TW5000 family of smart antennas. The new feature allows customers to align their antennas, standardize radiation patterns, and increase the synchronicity of their azimuth gain readings across multiple devices. The new north mark design has been thoroughly tested to ensure it conforms to or exceeds customer expectations and maintains each antenna’s stringent IP69K rating.

Protection Module
Adds resilience to critical GPS timing services

OtoSphere is a small, add-on module to the ViaLite GPS RF over fiber link and any GNSS-based system, providing GNSS protection against GPS jamming attacks, making any receiver more resilient. It ensures continuity of timing and navigation capability and enables normal operation during a jamming attack. According to ViaLite, no other solution that offers such protection is as small, light, affordable, or easy to install. The Otosphere protection module adds resilience to critical GPS timing services.Using OtoSphere, GPS receivers are up to 50 times more resilient to jamming attacks on positioning, navigation and timing (PNT) systems compared with having no protection. The GPS receiver can continue working normally throughout the attack. Timing-critical infrastructures in areas such as defense and cybersecurity can now be protected from these attacks. The Otosphere has a unique interference filtering algorithm that combines patterns from two external omnidirectional antennas that pinpoints the direction of the attack, then directs a null toward the unwanted signal to reject and reduce disruptions.

The Level 5 Control Tower (LV5 CTRL TWR)) is a mesh network of sensors and computers on infrastructure that guides vehicles autonomously without requiring that sensors be placed on individual vehicles. The technology is automating last-mile fleet logistics at BMW’s manufacturing facility in Munich. The system has the potential to transform operations for a wide range of business applications, from vehicle distribution centers to car rental companies and trucking logistics.

Savvy Navvy provides essential marine information, allowing boaters to cross-check their traditional navigation plans. It integrates plotting charts, weather and tide data, marina details and passage planning into one app. The app reduces the risk of human error as well as the stress of voyage preparation. It is used by boaters in more than 100 countries around the world, with more than 43 million miles plotted. It works on phones or tablets using Android, IOS, PC or Mac.

SURVEYING & MAPPING
RTK Rover
For IOS handhelds
Photo: Pix4D
The Pix4D viDoc RTK handheld rover attaches to iOS devices to bring RTK accuracy to terrestrial scanning on iPhones and iPads. When paired with the PIX4Dcatch mobile app, the viDoc rover can replace survey tools such as RTK GNSS rovers and terrestrial scanners, the company said. The two products create a workflow that turns iPhones or iPads into an accurate terrestrial scanning device, with centimeter-accurate RTK positioning from an existing NTRIP network. The tools can be used to 3D model small areas or structures.

Android Support
For laser-offset workflow
Photo: Bad Elf
Bad Elf now provides an integrated laser-offset workflow for acquiring high-accuracy field data in GNSS-challenged environments using Esri ArcGIS Field Maps for Android, as well as iOS. The workflow integrates Bad Elf and Laser Tech (LTI) hardware in collaboration with ArcGIS technology from Esri. The Bad Elf Flex connects to any LTI TruPulse rangefinder over a wired or Bluetooth connection to deliver high-accuracy location data to Esri ArcGIS Field Maps. Mobile workers can efficiently complete position and height data collection in access-limited situations, saving time, money and effort.

Global Map
For use in web applications
Photo: MapTiler
A free global map created from processed satellite imagery is available. To create the world image, satellite imagery was processed to remove clouds and balance shades and tones, and then carefully stitched together to create a seamless map layer with beautiful colors. The input data is recent, from 2020 and 2021, and rendered as one tiled file with 13 zoom levels 0-13 for use in web applications. It is a viable, up-to-date alternative to Google maps for software developers, without privacy issues.

GIS Platform
Shares 3D map datasets
Photo: MetaGeo
The MetaGeo geographic information system (GIS) platform enables organizations of all sizes to host, analyze, find and share 3D map datasets among any internet-capable devices. The platform processes location-based map or sensor data from the real world, combines it into a single 3D virtual environment, and streams it to any device or mapping platform. The affordable and easy-to-use platform can load data from multiple sources: satellites, drones, mobile devices, public and crowdsourced repositories, internet of things (IoT) sensor data, 3D models and topographic maps. The data is then processed by the MetaGeo platform into a 3D world and streamed to any internet-connected device, enabling live collaboration between the office and field via mobile or augmented reality device. A plug-in software development kit (SDK) allows for third-party tools to scale and fit user needs.

GNSS-inertial platform
For mobile mapping
Photo: Applanix
Trimble has launched the Trimble AP+ Land GNSS-inertial OEM platform for accurate and robust position and orientation for georeferencing sensors and positioning vehicles in land mobile-mapping applications. The platform enables users to accurately and efficiently track and monitor fleets and produce high-definition (HD) maps and 3D models. It can also serve as a reference solution for advanced driver-assistance systems (ADAS) testing, even in challenging GNSS environments. The comprehensive Trimble AP+ Land is small enough to integrate into compact mobile-mapping systems. It is compatible with virtually any type of mapping sensor, including single- or multi-lidar systems, video cameras, photogrammetric and panoramic cameras, and similar sensors.

Parallel Hybrid Electric Multirotor (PHEM) drone technology improves flight time with a heavy payload, yielding increased efficiency and eliminating the large battery used in other hybrids. It has the potential to extend a UAV’s flight time from 15 minutes to well over an hour and drastically increase range. In the search-and-rescue field, a heavy-lift drone can enhance first responder capabilities by allowing for substantially quicker response times to remote locations. Other applications include military platforms, fighting wildfires, and medical and logistics missions.
